Still in denial

I feel as if I am not progressing in this process as quickly as I should be.  My husband abruptly left after 14 yrs of marriage (16 together total) 6 months ago.  He moved in with another woman this week and I am still in denial.  I cannot process that he has left me and chose another woman.  Down deep inside I feel like he walked out of me and my daughters life because he knew he was hurting us with his alcoholism but just couldn't give it up.  I feel like he is just filling a hole with the new residence, girl, and dog.  Why am I not getting it?  Why aren't I angry, just sad?  My husband was head over heels about me and if anything everyone thought I would leave him first.  We are in the midst of a bitter divorce, mainly because of the safety and well being of our daughter.  I pray that I can move forward because the pain is becoming unbearable and I don't want to feel hurt anymore.  Is there any way to help this along.  I go to alanon and see a therapist but some days it feels like it just happened all over again.
